Webb's deepest spectrum of a little red dot — amplified by gravitational lensing to the equivalent of 80 hours of telescope time — reveals over 40 independent spectral lines all converging on the black hole star scenario: a rapidly accreting supermassive black hole buried inside a dense gas cocoon. The four-year mystery of these early-universe objects has its strongest answer yet.
